My possibly soon to be ex (m28) and I (f25) were due to be married less than a week ago.

We are very untraditional and spent the night before together, just talking and reminiscing on what got us to tat point. I’ve always known he is bi, and it’s never been an issue, it’s just who he is.

We have a very close knit group of friends, and he and his best friend grew up together and were one another’s support system throughout university. He’s been very open about all this since I first met him.

However, one thing I wasn’t aware of is that they were involved, and that my possible-ex is still in love with him, and the feeling is mutual. I asked him if he’d cheated on me before, and he confessed to ‘a few slipups’ but refused to go into detail.

The morning of the wedding I woke feeling sick and just totally overwhelmed and stressed. I was questioning everything that’s happened since we got together, and spoke to his best friend to confirm what I’d been told, which he did after an attempt to lie. I’ve cancelled the wedding and told him I need time to think, but I’m not sure I can get past the cheating.

I feel emotionally shattered. It’s only been a few days but his family and mine keep calling me trying to get me to feel guilty for my choice. We were paying for our wedding ourselves and it was a small, local affair, but I understand people might be disappointed that something they’ve waited for isn’t going to happen, possibly ever.
